| ultrastructure of the spermatozoon of the digenean lecithocladium excisum (rudolphi, 1819) (hemiuroidea: hemiuridae), a parasite of marine teleosts in senegal. | the present study describes the ultrastructure of the mature spermatozoon of lecithocladium excisum (rudolphi, 1819) (digenea: hemiuroidea: hemiuridae) from the stomach of the marine teleost scomber japonicus houttuyn (scombridae) captured in the atlantic ocean, off dakar (senegal). the ultrastructural organization of the spermatozoon of l. excisum follows the general model described in most digeneans. it presents two axonemes of the 9+'1' pattern of the trepaxonemata, nucleus, mitochondrion and ... | 2012 | 23136797 |
